In this paper, a control design method based on fractional order will be proposed for a multi-input multi-output (MIMO) process. To deal with the interactions between system variables, the decoupling technique using simplified decoupling is adopted. However, in this paper, the PSO algorithm is proposed to approximate the complex decoupled transfer function into a simple form of fractional-order transfer function. The tuning rules of a fractional-order PID (FOPID) controller are also derived analytically based on the internal model control (IMC) structure. To validate the proposed method in real applications, the identification of a multivariable process (MIMO), the quadruple tank system, is presented by using the diagonal form of matrix fraction description (MFD) which transforms a MIMO process into multi-input single-output (MISO) sub-models. Then, the proposed controller is simulated as well as implemented based on the identified models to illustrate the effectiveness of the proposed method.","PeriodicalId":345118,"journal":{"name":"2020 5th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130742244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to build a model of a simplified cerebellum neural network and investigate its working behavior in generating neuronal patterns. The model is constructed by referring to the neural anatomic structure of the mammal cerebellum and then simulated using Matlab Simulink software. The artificial neural network dimension is much smaller than the size of the real cerebellar neural network in mammal due to hardware simulation resource limitation. Thus, the utilization of extensivescale spiking neural networks is limited due to the grown of computational costs associated with propagating bio-realistic neural models. The parameters correlated with the neuron function also affect the biological plausibility of the spiking neural network. At the conclusion, we present the pattern generation of a cerebellum- like neural network and briefly explained why such patterns are generated.","PeriodicalId":345118,"journal":{"name":"2020 5th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133092206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A short-time Fourier transform algorithm is applied on heartbeats to produce frequency information, which can be seen as features of heart disease. Therefore, the features are the input of the multi-class support vector machine classifier for training and testing. In addition, the electrocardiogram signals are collected from the MIT-BIH database for this research, in which there are five types of heart disease with two cases of intra-and inter-patient.

Fourier-transform infrared spectroscopy analytical results showed that electro-Fenton was effective in textile dyeing wastewater treatment due to its ability to decompose and transform dyes and cyclic compounds. From experiments on effect of FeSO4 and NaCl amounts, it is discovered that the removal efficiencies of color and COD fluctuated depending on the amounts of two chemicals. And, the suitable conditions for high color removal in batch electro-Fenton model including a 24V-10A of DC power supply and a 100 cm2 of MMO electrode was found to be in pH range 2 – 4, with the dosage of FeSO4 and NaCl are 1 and 15 g, respectively for 3 L of wastewater. Besides, the efficiencies of color and COD removal from SR dyes were higher than those from SB dyes. On the contrary, the SB’s decolorization rate was faster than that of SR through the difference of the rate constant obtained from kinetics study.","PeriodicalId":345118,"journal":{"name":"2020 5th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126155228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increase in sprue height from 3 mm to 7 mm would achieve the highest stamp temperature with the height of 3 mm.
